B UNG AND BUSHING.

SPECIFICATION To all whom it may concern.-

Be it known that I, JOSEPH PARRISH BAUM- GARTNER, a citizen of theUnited States, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Bungs andBush ings, which'improvement is fully set forth in the followingspecification and accompanying drawings.

My invention consists of a novel construction of bung, and a bushingtowhich the same is applicable, provision being made for readily expandingthe desired portions of said bung against its bushing, and means beingalso provided for limiting the movement of the expanding device.

It also consists of a novel construction of wrench.

It further consists of novel details of construction, all as will behereinafter set forth.

Referring to the drawings: 1 designates a portion of a cask or barrel,and 2 a flanged forming part of Letters Patent No. 541,651, dated June25, 1895. Application iiled April 6, 1895. Serial No. 544,720. (Nomodel.)

bushing which is adapted to be secured thereto, said bushing having itsinner portion 3 tapering,'the widest portion being within, and theportion 4 thereof being of uniform diameter, said bushing having alsothe bevel 4* at its outer portion;

designates inclined slots in said bushing which are located preferablydiametrically opposite each other, and adapted to receive the lugs 6,which are in the present instance inclined, and attached to the outerwall of the cup shaped receptacle 7, the same consisting f the topportion or flange 8, the circular wall 9 attached thereto, and thediaphragm or partition 10 attached to said wall, the same having thehole 11 therethrough, in which the enlarged portion 12 of the hollowexpanding sleeve 13 is nicely fitted, so as to turn freely therein,.said bung having a beveled portion 5 which contacts with the face 43 ofthe bushing.

14 designates a curved recess in the upper surface of said diaphragm 10,which is adapted to receive the lug 15, which is attached to the innerside of the flange or disk 16 which is mounted on the hollow sleeve 13,the walls 17 :and 18 of said recess 14 limiting the move- -ment of saidlug 15, which latter thus'serves as a stop, as will be hereinafterexplained.

The diaphragm 10 has a curved slot 19 therethrough, in which is adaptedto be placed the curved bar 20 the shape of which will be clear 3 fromFig.112, a face of said bar having attached theretothe lug 21, which isadapted to enter either the recess 22 or 23 of the disk 16, as will beexplained.

The construction of the expanding sleeve 13, which is best seen in Fig.5, will now be described, the same consisting of the hollow shell 24, onwhich are mounted the cams 25, 26, 27 and 28, which are arrangedrelative to each other, at substantially angles of ninety degrees in thepresent instance, as will be understood from Figs. 5 and 7 to 9,thelongest axis or diameter of each of the above cams being, it will benoticed, substantially the same as the diameter of the enlarged portion12 so that the sleeve 13 can bereadily slipped through the hole 11 inthe diaphragm 10. The top or outer face of the disk 16 has attachedthereto the bar 29, which has the hole 30 therethrough, which is inalignment with the hole 31, which extends clear through the shell 24,and has inserted therein when the parts are in assembled position, thestem 32, one end of the latter being attached to a disk 33, whosestructure Will be evident-from Fig. 3, the other end of said stem havinga groove 34 therein, which is adapted to be engaged by an end of thethreaded stud 35, which is screwed into the hole 36 of the solid portionof the bar 29, it being noticed that the other end of said bar has aportion cut out from under the same, thus forming the lip 37.

38 designates a hole in the wall of the cup 7, through which the stud 35is inserted in assembling the parts.

39 designates the cam plates employed, whose construction will beunderstood from Fig. 13, the same being applied to the faces of theirrespective cams in pairs, as will be understood from Fig.8, the outerface of said cam plates thus forming a true circle when they are intheir normal position, while their inner edges conform to the outline ofthe cams, 25, 26, &c.,it being evident that two of the latter may beemployed if desired, instead of four, as seen in Fig. 5, the number ofsaid cams to be increased or diminished according to requirements. Thesaid plates 39 are provided in the present instance with the recesses40, which engage projections on the ring or rings 41,a washer 42 seen inFig. 3, being employed to fill in the space between the cam 25 and thedisk 33.

42 designates the wrench employed, the same consisting of the handle 43,and the head 44, said head having on the bottom thereof the annularprojection or ring 45, which has portions removed at the points 46,diametrically opposite to each other, the width of said portions beingequal to the width of the bar 29, as will be understood from Fig. 10. 47designates lugs attached to said ring 45 of substantially the same shapeand distance apart as the openings 22 and 23 in the disk 16, it beingnoticed that one of said rings 45 has a cut-away portion forming the lip48, which is adapted to be inserted under the lip 37 of the bar 29, therelative position of the above described parts being evident from Fig.11.

The under side of the diaphragm 10 is provided with the recesses 49 and50 and the ribs 51, which are in contact with the ring 41, as seen inFigs. 3 and 7.

The operation is as follows: The parts are assembled by first placingthe hollow sleeve 13 within the cup 7, the lug 15 being within therecess 14. The curved bar or looking device is now placed in theposition seen in Fig. 6,whereupon it will be evident that the lug orprojection 21 will enter either the hole 22 or 23, as seen in Fig. 1.The rubber ring or rings 41 are now placed in position against the underor inner face of the partition 10, the bar 20, being held in place bymeans of said rings and the cam plates 39 are placed in position againsttheir respective cams,a pair of plates in the present instance beingapplied to each cam, as stated. The stem 32 is then inserted through thesleeve 13, and the disk 33 thereon is brought up against said ring 4],after which the stud 35 is inserted through the hole in the wall 9, andscrewed in until its end engages the groove in the stem 32, the end ofthe latter being flush with the outer face of the bar 29, the partsbeing new in the position seen in Fig. 3.

To expand the hung, the wrench 42 is applied thereto, in the manner seenin Fig. 10, the lip 48 engaging the lip 37, the lugs 47 being now inalignment with the holes 22 and 23, and it now the handle is presseddown, as indicated in Fig. 10, one of the lugs 47 will be brought intocontact with the lug 21, and the latter will be depressed below the faceof the flange 16, as seen in Fig. 10, and the bar 29 and the expandingsleeve 13 can then be rotated into theposition seen in Fig. 9, therelative position of the cams and cam plates being seen therein, thering or rings 41 being now in their expanded position and tightly incontact with the bushing, the cup 7 being kept from rotating by theengagement of its lugs 6 therewith, and the extent of movement of thedisk 16 being limited by the contact of the lug 15 with the walls 17 and18 of the recess 14, said lug l5 reaching one or the other of saidwalls, when the cams and plates are in the position seen inFig. 9, thelug 21 entering either the opening 22 or 23 in the partition 16 at theend of the movement of the latter.

I desire to call especial attention to the fact, that when the ring 41is expanded, the same is prevented from rotation by the engagement ofthe ribs 51 with the adjacent face of said ring, said ribs and cup7beingprevented from rotation as has been explained.

The wrench 42 can be employed for lifting the hung from the bushing,when the same is applied as seen in Fig. 10, the lip 48 being insertedunder the lip 37, a shoulder 48* being formed adjacent said lip 48.

It will be evident that if desired, the notches may be omitted from thecam plates 39, and I further reserve the right to make such otherchanges as will come within the scope of my invention, and I thereforedo not desire to be limited in every instance to the exact constructionI have herein shown and described.
